Corrie was knowledgeable,passionate and masterful in her subject matter.highly recommended.would love to do more tours with her,such as the whiskey tour. As an aside,when we visited the Heinz museum on Friday morning,there were only 2 other visitors in the building. I went to the men’s room on the second floor. It was empty and just been cleaned. As I was at the sink, several of the automatic toilets began to flush. Startled,I went to look,no one was there.On my honor!!!!!!
